Comparison of structurally-related alkoxide, amine, and thiolate-ligated MII (M=Fe, Co) complexes: The influence of thiolates on the properties of biologically relevant metal complexes

Autor: Lisa M. Brines, Julie A. Kovacs, Priscilla Lugo-Mas, Werner Kaminsky, Jason B. Benedict, Terutaka T. Kitagawa, Rodney D. Swartz, Gloria Villar-Acevedo

Publikováno v: Inorganica Chimica Acta. 361:1070-1078

Mechanistic pathways of metalloenzymes are controlled by the metal ion’s electronic and magnetic properties, which are tuned by the coordinated ligands. The functional advantage gained by incorporating cysteinates into the active site of non-heme i

Water-Soluble Fe(II)−H2O Complex with a Weak O−H Bond Transfers a Hydrogen Atom via an Observable Monomeric Fe(III)−OH

Autor: Martin L. Kirk, Werner Kaminsky, Lisa M. Brines, Michael K. Coggins, Julie A. Kovacs, Penny Chaau Yan Poon, Santiago Toledo

Understanding the metal ion properties that favor O-H bond formation versus cleavage should facilitate the development of catalysts tailored to promote a specific reaction, e.g., C-H activation or H2O oxidation. The first step in H2O oxidation involv

Understanding the Mechanism of Superoxide Reductase Promoted Reduction of Superoxide

Autor: Julie A. Kovacs, Lisa M. Brines

Publikováno v: European Journal of Inorganic Chemistry. 2007:29-38

Superoxide reductases (SORs) are nonheme, iron-containing enzymes which reduce superoxide (O2 ‐ ) to hydrogen peroxide (H2O2) in anaerobic organisms. In contrast to the classical superoxide dismutases (SODs), SORs selectively reduce, rather than di

Synthesis and Structural Characterization of a Series of Mn(III)-OR Complexes, Including a Water-Soluble Mn(III)-OH that Promotes Aerobic Hydrogen Atom Transfer

Autor: Lisa M. Brines, Julie A. Kovacs, Michael K. Coggins

Hydrogen-atom-transfer (HAT) reactions are a class of proton-coupled electron-transfer (PCET) reactions used in biology to promote substrate oxidation. The driving force for such reactions depends on both the oxidation potential of the catalyst and t

Understanding How the Thiolate Sulfur Contributes to the Function of the Non-Heme Iron Enzyme Superoxide Reductase

Autor: Lisa M. Brines, Julie A. Kovacs

Publikováno v: ChemInform. 38

Toxic superoxide radicals, generated via adventitious reduction of dioxygen, have been implicated in a number of disease states. The cysteinate-ligated non-heme iron enzyme superoxide reductase (SOR) degrades superoxide via reduction. Biomimetic anal
